Patented Oct. 1, 1946 I UNITED STATE TOGGLE BOLT 2 Claims.

This inventionrelates to a toggle bolt and .more particularly to a toggle bolt which may be utilized'in attaching various articles to a hollowwall and used in effecting arepair in a wall of a tankorsimilar. structure.

- P pal objectof the invention i th provision of a toggle bolt insertable through an opening in a hollow wall or hollow article and operatable to engage the inner surface of said wall or article. V

'A further objectof the invention is the provision of a toggle bolt, thetoggle portion of which is capable of beingjpositioned in axially extending relation to V the bolt portion thereof.

' A still further object of the invention is the provision of a toggle bolt, the bolt portion of which is provided with a transversely formed opening and a longitudinally extending slot associated therewith for the accommodation of a semi-L shaped toggle.

A still further object of the invention is the provision of a toggle bolt construction which may b effectively used in effecting a fastening to a hollow wall or a, hollow article or which may be used in joining two adjacently positioned members to one another.

The toggle bolt shown and described herein has been designed to form a more effective toggle bolt construction than has been'heretofore available for the various indicated purposes. The rtoggle bolt shown and described herein is constructed essentially of two relatively large and heavy structural parts, one of which is positioned partly in a transversely formed opening in the other and is therefore pivoted in relation thereto and which is capable of being positioned in transverse relationship to the other and employed as an anchor in a hollow article. The

. toggle bolt shown and described herein may be effectively used in connection with plugging openings in tanks and similar containers and in providing fastening means on large hollow articles or onhollow walls.

With the foregoing and other objects in view which will appear as the description proceeds, the.

2 Figure 1 is a cross sectional side elevation of -a toggle bolt showing the same in connectionwith a resilient gasket assembly and mounted in insertable position in an'opening in an article.

Figure 2 is a cross sectional side elevation of the toggle bolt illustrated in Figure 1 and shows [the same inoperative position plugging the opening through which it has been inserted. I

Figure 3 is an end elevation of the toggle bolt ofFigure 1. h

Figure 4 is an end elevation of the inserted toggle bolt taken on lines 4-4 of Figure 2.

Figure 5 is a sideelevation with parts in cross section and parts broken away illustrating the toggle bolt utilized as a joiningmember or in attaching one article to another.

By referring to the drawing and Figures 1, 2, 3 and 4 in particular it will be seen that the toggle bolt consists of a threaded bolt portion I0 having an unthreaded end section I I' which is provided with a transversely formed opening I2 and a longitudinally positioned slot I3. The slot it extends from an end M of the unthreaded end section] II of the; bolt to communicate with the transversely positioned opening I2 therein. An enlarged annular area [5 is formed on one side of the unthreaded end I I of the bolt I and adjacent to and in communication with the transversely' positioned opening I2. Positioned in the transversely positioned opening I2 and the slot I3 and annular area I5 there is a semi-L shaped toggle I6 which is provided with a head I! on its semi-L shaped end and with a transversely positioned pin or stop member l8 near-its other end. As illustrated in Figures 1 and 2 of the drawing, the threaded bolt portion In of the toggle bolt assembly carries a resilient gasket I9, a concave washer 20 and a threaded nut 2|, which nut 2| engages the threaded bolt I0 so as to move the concave washer 20 and the resilient gasket I9 against an article such as is indicated by the numeral 22 through which article 22 the toggle bolt is positioned by means of inserting the same through an opening 23 in the article It will be observed by referring to Figures 1 and 3 of the drawing that the toggle I6 in axially extending position in relation to the bolt Ill occupies an area of smaller diameter than the diameter of the bolt I0 itself. The construction thus provided is capable of insertion through I a relatively small opening such as 23 in the article 22 and at the same time enables the toggle portion I8 of the toggle bolt to be of relaposition taken on lines 3-3 tively large size in relation to the remainder of the bolt 10 and hence be capable of providing a sturdy, durable anchor for the toggle bolt.

By referring now to Figures 2 and 4 of the drawing it will be seen that the toggle bolt upon being inserted, as illustrated in Figure 1, has been rotated so as to cause the headed end I! of the toggle IE to drop downwardly out of the transversely positioned opening l2 in the bolt l and thereby swing the majority of the toggle l6 into vertical position with respect to the horizontally positioned bolt I0. serves to hold the toggle It in appropriate position, as illustrated in Figures 2 and 4, and this vertical positioning is indicated to the manipula- The pin or stop member I8 tor of the device by the appropriate positioning of a screw driver slot 24 formed in the end of the threaded bolt Ill. The bolt 10 may, therefore, be held in stationary position through the screw driver engaging the slot 2d while the nut 2| is turned against the concave washer so as to compress the resilient gasket H) as shown in Figure 2.

By referring now to Figure 4 of the drawing, an end elevation of the properly positioned toggle bolt assembly may be seen and it will be observed that the pin or stop member [8 positioned transversely of the toggle it supports the same in vertical position on the threaded end H of the bolt l9 and thereby enables the device to offer a satisfactory, broadly spaced anchor which will suitably support the toggle bolt with respect to the tension applied thereto as by the tightening up of the nut 2|.

It is obvious to those skilled in the art that the toggle bolt construction shown and heretofore described herein may also be used in attaching it to hollow walls or hollow wall articles and in which use the resilient gasket is neither indicated nor desirable.

By referring to Figure 5 of the drawing such use of the toggle bolt construction may be seen wherein an article is shown held in position against a supporting wall or structure 26, which wall or structure is provided with an opening 21 therein. The toggle bolt shown in Figure 5 consists of a partially threaded bolt 28 having an unthreaded end section 29 and a toggle 3D positioned transversely therein in the manner illustrated and described in connection with the toggle bolt construction shown in Figures 1 through 4 and heretofore described. A nut 3| threadably positioned on the threaded bolt 28 enables the device to be pulled together as in attaching the article 25 to the article 26, it being observed that the portions of the toggle 30 are broken away in the drawing, and further that the toggle 30 provides a suitable anchor bridging a considerable area on the inner side of the article 26 to satisfactorily mount the article 25 thereagainst. This construction and that illustrated in Figures 1 through 4 of the drawing make advantageous use of the relatively large sized toggle portions l6 and 36, respectively, for providing a secure and dependable toggle bolt construction of long life not dependent upon any small, readily destructible portions.

It will thus be seen that a toggle bolt which may be economically fabricated of simple parts and hence widely distributed at low cost and ad vantageously used due to its simple operating characteristics and dependable on installation has been provided.

' Having thus described my invention, what I claim is:

1. In a fastener, a partially threaded body member adapted for insertion through openings in articles to be fastened, a nut threaded on said threaded body member, an opening formed transversely in the unthreaded portion of the said body member, and a slot formed between the said opening and the unthreaded end of the said member, a toggle having a curved headed end freely positioned in said opening and pin means inwardly from the other end of said toggle for limiting its movement with respect to the said body member.

2. In a toggle bolt,a partially threaded body member having a transversely formed opening in the unthreaded portion thereof near the unthreaded end thereof and a slot formed between the said transversely positioned opening and the said unthreaded end thereof, a toggle member consisting of a section of round material curved at one end and provided with a head thereon freely positioned in said opening and capable of movement therein, pin means on said toggle for preventing it from falling out of the said body member, and a nut threadably positioned on the threaded portion thereof.
